A rainy weekend is expected in parts of Saskatchewan, with up to 80 millimetres of rain possible in some areas by Saturday night.

Environment and Climate Change Canada (ECCC) issued a rainfall warning for a portion of west central Saskatchewan around 3:30 p.m. on Friday.

According to the warning, showers will begin late Friday evening and overnight before turning into heavy rain on Saturday morning. The weather agency says the heavy rain will continue during the day but will taper off in the evening.

As of Friday afternoon, the warning covered areas including Kindersley, Eston, Rosetown, and surrounding regions.

Increased runoff

In an advisory Friday afternoon, the Water Security Agency (WSA) said the large amounts of rain is likely to increase runoff into the South Saskatchewan River, as well as other bodies of water between Lake Diefenbaker and the western border.

WSA advises people to take precautions around lakes and rivers, making sure to be aware that water levels can change quickly and without warning.

WSA asks the public to check local conditions before venturing on or near bodies of water and says it will provide updates as necessary.
